It is hard to convey how "sustainable" this feels to me. For the first time, humans have gone into orbit in a spacecraft that was designed from the ground up to be a commercial venture. All of the NASA missions prior to this have an ambience of "uneconomical but useful". Even the shuttle, which was supposed to be this cost effective space truck, turned out to be not even close. And the last thing I'm feeling is the a…

A new normal has just been defined. Amazing to see. "Thank you for flying with Falcon 9 today", as though it's an airplane.

Wouldn't it be "Thank you for flying with Spacex today"?

I think it's the general problem of infrastructure-like endeavors. "If you build it, they will come" absolutely applies to infrastructure.

"If you build it, they will come" suffers from confirmation bias. You can easily look back at things people have built and people have come to (computers, planes, cars, etc)... But there are far more things people built that no one came for, and which we don't even know of because no one wanted them. Solar roadways is an example of something that was an infrastructure project that was built out in a few places, and b…

Weren't solar roadways just bullshit and rather thoroughly debunked from the engineering POV from the very start? Concorde also AFAIR was a victim of oil prices.

There is perhaps a bit of confirmation bias in this view, but I see people usually erring in the other direction. E.g. there's no such thing as "too fast Internet" today, people find new ways to suck up all available bandwidth.

Best video found so far of it that covers launch and landing of falcon 9. Alas loss of signal during the moment, though I'm sure another camera angle/footage will come about. https://www.youtube.com/watch?v=-JPLgs3ktyo

I've already seen conspiracy theorists online who claimed that loss of signal during every first stage landing is a proof that it's all a hoax. Like, they switch footage to another droneship with a rocket that was always there. I wonder if these people believe in flat Earth, too?

I've seen a few missions where the link didn't fail and viewers got to see it come down onto the droneship. It sure seems to be a crapshoot whether the link stays up for the landing, though.

>> into orbit in a spacecraft that was designed from the ground up to be a commercial venture. If we are talking pure commercial travel, it is a vehicle without a destination. The ISS is definitely not a commercial project. There are lots of reasons for the ISS to exist, and they have changed over time, but it has never been a money-making venture. While the dragons certainly do come in under budget, they are a more…

I’m not super well informed on this, but is there any reason for sending humans to space at this moment in time (or for the next 20 years for that matter). The only reason my layperson understanding can think of is mining minerals in space, but I fail to see why robots wouldn’t be able to adequately do the job. In fact wouldn’t sending humans make future space ventures even more costly and put people into unessisary…

That's a fair point. Hell, I'd argue that half the interest in spaceflight (except those of people seeing it all through the lens of an Excel sheet) is because of the idea of sending people up there. That alone makes an occasional manned mission worth it, just to keep the general interest alive.

It is not the 1910s any more. We don’t risk other peoples lives on exploration. Heroic though it might seem, it is ultimately foolish. We are already exploring the solar system with machines. And there is no reason to risk the explorers life for a more limited and more expensive ways to explore.

> And there is no reason to risk the explorers life for a more limited and more expensive ways to explore.

In places that can be reached by both, it's the machines that are much more limited. Compare e.g. the distanve covered by astronauts on the Moon in a day with the distance covered by Martian rovers in a year. There's a benefit in local decisionmaking instead of a remote one over a very bad link.

I'm actually surprised they use a touchscreen interface, and they will use that for the manual docking too! https://i.imgur.com/YKiqIqO.jpg

You can try out the docking maneuvers in this official minigame: https://iss-sim.spacex.com/

Personally I found the lack of analog input control harrying toward the end. A toggle between "large" and "normal" thrust mode is all you get. Normal felt like it wasn't fine-grained enough.

I understand your sentiment, but I’m also profoundly unsettled by the idea that commerce and capitalism are reaching beyond the clutches of our planet. Today is definitely a threshold, but what that threshold means, in a broader sense, is not clear to me.

As liberals we celebrate the entrepreneurial slam-dunk and as technologists we admire the elegant engineering.

But maybe I’m jaded, but I fear the profit motive is going too far. We live in a truly extraordinary moment socioeconomically. Never before in the history of mankind had so much activity been predicated upon commercial viability — and never before had so much gone undone simply because it is unprofitable.

Spacefaring nations’ governments have not abdicated spaceflight, and indeed they’re likely to militarise their approach ever more. But now we have private enterprise ferrying people up there too.

“Sustainable”... what a funny word. When have commercial ventures ever been “sustainable”? A sustainable commercial venture tends to be one that externalises most of its costs (look at the sustainability of bulwarks of 20th century commercial ventures, such as the automotive industry and its bedfellow oil & gas).

I will say I’m glad that manned spaceflight is no longer the prerogative of a couple of extraordinarily well-heeled superpowers. But...

Thinking of Europe, I have a feeling that it's just surreal that this launch is happening in America at the same time with the events in Minneapolis

Nice... I had this one kicking around in my head
